I try to characterize generated SRAM model, but see a wall of fail's on "Port 1" only ("Port 0" are ok). And this is don't going to sctipt terminate. Version: 1.2.40 To reproduce, run this config:
word_size = 32 # Bits num_words = 32 human_byte_size = "{:.0f}kbytes".format((word_size * num_words)/1024/8) write_size = 8 # Bits num_rw_ports = 2 num_r_ports = 0 num_w_ports = 0 num_spare_rows = 0 num_spare_cols = 0 esp_name = "esp_aux_dual" delay_chain_stages = 21 verbose_level = 1 tech_name = "sky130" nominal_corner_only = True route_supplies = "ring" #route_supplies = "left" check_lvsdrc = True uniquify = True #perimeter_pins = False netlist_only = True analytical_delay = False num_threads = 4 num_sim_threads = 8 ports_human = "{0}rw{1}r{2}w".format(num_rw_ports, num_r_ports, num_w_ports) output_name = "{tech_name}_sram_{human_byte_size}_{ports_human}_{word_size}x{num_words}_{write_size}".format(**locals()) output_path = "macro/{output_name}".format(**locals())
Expected: Same behaviour into both ports. Log:
